100 years of Albert Einstein General theory of relativity

The Croatian Post Ltd. Mostar issued a commemorative stamp to celebrate 100 years of Albert Einstein General theory of relativity.

The stamp features the most famous photo of Albert Einstein and his famous equation E = mc².

Albert Einstein (1879. – 1955.), one of the greatest scientists of the 20th century, is most famous by his theory of relativity by which he introduced a revolution to modern physics.

About Albert Einstein

ALBERT EINSTEIN IS ONE OF THE MOST FAMOUS, ICONIC, INFLUENTIAL AND UNIVERSALLY ADMIRED PERSONS IN HUMAN HISTORY.

Albert Einstein was born at Ulm, in Wurttemberg, Germany, on March 14, 1879. Six weeks later the family moved to Munich, where he later on began his schooling at the Luitpold Gymnasium.

Later, they moved to Italy and Albert continued his education at Aarau, Switzerland and in 1896 he entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics.

In 1901, the year he gained his diploma, he acquired Swiss citizenship and, as he was unable to find a teaching post, he accepted a position as technical assistant in the Swiss Patent Office. In 1905 he obtained his doctor’s degree.

He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).

Einstein is best known in popular culture for his mass–energy equivalence formula E = mc².

He received the 1921 Nobel Prize in Physics for his “services to theoretical physics”, in particular his discovery of the law of the photoelectric effect, a pivotal step in the evolution of quantum theory.

Albert Einstein General theory of relativity

The theory of relativity is named this way because according to it absolute greatnesses do not exist rather everything is relation to one another, and consists of two scientifically theories in the physics field: special relativity and general relativity.

General theory of relativity is a geometric theory that suggests that the presence of mass and energy „curves“ space-time (physical concept that fuses space and time dimensions in one matter), and curvature impacts the way of free particles.

One hundred years after Einstein’s General theory of relativity, in February 2016, scientists from Columbia University (New York) confirmed the existence of gravitational waves.

This revelation confirmed Einstein’s final unconfirmed theory according to which gravitational waves move at the speed of light in a vacuum and have deviation in space.

Evidence that gravitational waves exist proves Einstein’s theory that the term space-time is not emptiness but yet four – dimensional „fabric“ that could be stretched in cases in which objects pass through it.
